Stabilized electrocoagulation printing ink

摘要

A stabilized electrocoagulation printing ink comprises a liquid colloidal dispersion containing an electrolytically coagulable collloid, a dispersing medium, a soluble electrolyte, a coloring agent and a sequestring agent for complexing metal ions generated during electrocoagulation printing. The sequestring agent is present in an amount to prevent the metal ions from causing the colloid to undergo undesirable cross-linking, without adversely affecting electrocoagulation of the colloid.
